3.3 V, 280 MHz LVPECL
Clock Oscillator
The NBXSBB020/NBXSBA020 single frequency crystal oscillator
(XO) is designed to meet today's requirements for 3.3ĂV LVPECL
clock generation applications. The device uses a high Q fundamental
crystal and Phase Lock Loop (PLL) multiplier to provide 280 MHz,
ultra low jitter and phase noise LVPECL differential output.
This device is a member of ON Semiconductor's PureEdget clock
family that provides accurate and precision clock solutions.
Available in 5 mm x 7 mm SMD (CLCC) package on 16 mm tape
and reel in quantities of 1,000. Frequency stability options available as
either 50 PPM NBXSBA020 or 20 PPM NBXSBB020.

NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 Ifpm. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
3. Measurement taken with outputs terminated with 50 ohm to VDD-2 V. See Figure 4.
4. Parameter guarantees 10 years of aging. Includes initial stability at 25°C, shock, vibration, and first year aging.
